Build me a tf2 item Coinflip jackpot site

Job ID: 30891195

Budget: $500 – $1,100 USD

I'm in need of someone who will create me a small tf2 item betting site with two main components - the coinflip and jackpot mini game. This site would involve players signing in via Steam (using steam api) then allow them to deposit their in-game skins worth an amount of $$$ equal to that generally accepted price for the item(IE a Mann Co Key is 2.49, but an Unusual with a specific particle effect has a community driven price). This is generally found on backpack.tf. These items would not be stored (steambot should only hold profit held by house; users play head to head where items are delivered back from not to winner immediately)

However, before the players can actually sign in, there will be a small check box ensuring the player is of the age of 18 or older in the same window that allows them to sign in. If they do not check this box, they cannot sign in. Once this is done, the players could then either choose to open a coinflip, or join a jackpot.

The Coinflip will have a minimum of 1$ to maximum of 5000$; one player vs one player. Creator of the flip chooses what side of coin they wish to play as.

(Player A who creates flip deposits items worth value X on coin T, Player B joins flip with value match of X within 10%(bet value Y), winner gets X+Y in value minus 5%(house tax) of value that would remain in the steam bot)

If player B's bet is not equal to the original game, skew the odds in either favor(if player a bet 40$ and player B bets 45$, player b has slightly better odds over 50% to win).

An animation script will need to be created for the coin flipping (using the player's steam profile picture on the coin's sides.),

A simple jackpot will be needed, with the same 5% house tax as the Coinflip game. However, the jackpot will allow up to 35 items worth minimum $0.50 maximum 2500$.

The jackpot allows any number of players to enter, where the more value you enter compared to the other players, the higher your chance to win.( Player 1 bets 10$, player 2 bets 20$ and player 3 bets 5$. Player 2 has the highest chance to win, with player 3 having the lowest).

This is called a "pot", a temporary cache of players items. It should be time limited (50 seconds) where any bets placed before time ends will be accepted, highest $$ has the highest win % but doesn't always win.

(Preferred that the more % to win pot a player has, the more their picture appears)

The wheel will spin and gradualy slow down and the winner's profile picture will land on an arrow placed in the middle of the wheel or slider

Both the Coinflip and jackpot need to be probably fair, and payout to the winner immediately.


The items used for monetary value are teamfortress 2 items, thus the deposit and payout must be handled by a steam bot. I can provide accounts but I need the bot handled by developer. This means knowledge of steamapi
